The element that has the largest atomic radius is cesium. It has an atomic radius of 298 pm, or picometers. An alkali metal, cesium is so active that it instantly explodes if dropped into cold water. It's also one of the few metals that becomes a liquid at close to room temperature. Its melting point is 83.19 degrees Fahrenheit.
One of cesium's most important functions is as the basis for the atomic clock. Cesium is used to calculate the length of a second. This is done by beaming a signal of a certain frequency through isolated cesium atoms.
Cesium is also used as a "getter," which means that it will remove any trace of oxygen or water from a vacuum tube. It's also used in oil well drilling to clear any leftover chips of rock. Cesium has also been used to sterilize surgical equipment, food and sewage.
Cesium is a fairly rare element on earth, but it's more abundant than silver, mercury or even tin. It's most often found in pegmatite ores. One of the richest sources of this ore is in Manitoba, Canada.
The atomic number of cesium is 55. Its atomic weight is 132.90545, and its density is 1.879.Learn More
The chemical reaction for the burning of sugar by the body is shown through the chemical equation C12H22O11(s) + 12 O2(g) -----> 12 CO2(g) + 11 H2O(l). In this equation, C12H22O11 is the sugar, which burns by reacting with the oxygen to create carbon dioxide and water.Full Answer >
According to Home Guides, chlorine lock, or stabilizer lock, is a term misused by uneducated providers of pool advice. Stabilizer is a critical part of the important oxidation and reduction potential for the pool to maintain effective sanitation. Home Guides provides a guide on how to maintain a pool using stabilizer.Full Answer >
Chemistry performed in the liquid phase is defined as wet chemistry. The term "wet chemistry" is synonymous with "bench chemistry" because the experiments are often performed at a chemistry bench. Wet chemistry involves the use of beakers, flasks and other glassware to perform general experiments.Full Answer >
Diffusion is the net movement of a substance from a region of high concentration to a region of low concentration. The difference between concentrations in a space is a "concentration gradient." As explained by The Biology Corner, molecules will always move down a concentration gradient toward areas of lesser concentration.Full Answer >
